In a recent letter to his community, Massachusetts Institute of Technology President Rafael Reif criticised President Trump's decision to exit the Paris climate agreement, for ignoring "consensus" climate change science. In reply, a group of skeptic scientists have penned a two-part explanation of why Professor Reif is wrong, and why the ParIs agreement is a bad deal for America (and, by implication, any other first world nation unwise enough to sign up to it). The skeptics' reply is in two parts, and is a brilliant refutation of the alarmist propaganda.
